It's unfortunate about the OPs problems with a new 16in MBP. I suspect that it could be returned and the replacement will be fine.
If you search MR, there are a fair number of complaints about the 16in MBP. I am sure most of these will be resolved and the customers will ultimately be satisfied. However, this does prove a larger point. For months, I read from posters about how this was going to be the perfect Mac, and how people that bought earlier models were idiots. This was going to be the MacBook that solved the keyboard issues and would not have problems of its own. There is no such thing. Apple makes millions of these laptops. All designs have weaknesses and all production processes produce some failures. Expectations were set too high. And now, the echo chamber of discontent has turned its attention to this product.
